I can't r-word today. Obviously, you take the tape measure to the size of the cage you're looking at online to get an in-person look at how large the cage would be.
I know you're smarter than that, but my tolerance is real low today.
Honestly, a 30x18x18 flight cage would be better than that. You could do 30x18x36 if you wanted. That size is less expensive than some of the other cages, as the gauge on the wire is smaller because it doesn't need to hold up to strong beaks.
The dowel perches are alright if other perches...
